Emergency Cyber Incident Response Services
Cyber incident response services provide 24/7 emergency support when an organisation is experiencing an active attack, ransomware infection, data breach, or system compromise. A specialist incident response team contains the threat, conducts forensic investigation to determine scope, eradicates attacker persistence, and coordinates recovery, typically with remote containment initiated within 30 minutes of first contact.
Our incident response team is available now. We contain active attacks, recover encrypted environments, and guide you through GDPR notification. Remotely within 30 minutes, on-site within 4 hours across the UK. CREST accredited. 500+ incidents resolved. Do not restart systems. Do not pay the ransom. Call us first.

Our Cyber Incident Response Services
Rapid containment and recovery following NIST SP 800-61 incident response framework. Every action preserves forensic chain of custody.
Immediate Containment (Under 1 Hour)
First responders arrive remotely within 30 minutes or on-site within 4 hours to contain the breach: isolating compromised systems, blocking attacker IP addresses, disabling compromised accounts, and preventing lateral movement across your network.
Ransomware Triage and Recovery
Emergency response to ransomware attacks: determining encryption scope, identifying the ransomware variant, assessing backup viability, and coordinating decryption or recovery from clean backups. We maintain current recovery procedures for all major strains.
Active Threat Hunting
Hunting for persistence mechanisms, backdoors, and other compromised systems while the attacker may still be in your environment. Ejecting the attacker permanently to prevent re-infection.
Business Continuity Support
Coordinating with your IT team to restore critical services while maintaining forensic integrity. Prioritising systems based on business impact to minimise operational downtime and meet RTO targets.
Legal and Regulatory Guidance
Advising on regulatory notification requirements including GDPR Article 33, NIS Regulations, coordinating with cyber insurance providers, and engaging law enforcement where appropriate.
Emergency Response Process
From initial call to full recovery.
Emergency Call and Mobilisation
Call our emergency hotline. Our incident response team is mobilised immediately. Remote access is established within 30 minutes.
Triage and Containment
Rapidly assessing the scope of compromise and implementing containment measures: network segmentation, credential resets, endpoint isolation, and blocking command-and-control (C2) traffic at the firewall.
Eradication and Recovery
Removing attacker persistence mechanisms (scheduled tasks, registry keys, web shells), restoring systems from clean backups, and implementing hardening measures to prevent re-infection.
Post-Incident Forensics and Reporting
Comprehensive incident report documenting attack timeline, root cause, data accessed, and remediation steps. Supports GDPR breach notification, insurance claims, and board-level communications.
Data Breach Response and GDPR Notification Support
The GDPR 72-hour notification clock starts from the moment you become aware of a breach, not when the investigation completes. Our forensic triage is structured around the ICO's requirements so you can notify with confidence.
72-Hour ICO Notification
Within the first four hours of engagement we provide a preliminary breach assessment covering what systems were accessed, what data categories were at risk, and whether the incident meets the Article 33 notification threshold.
Article 33 and 34 Compliance
Our incident reports are structured to meet the ICO's breach notification template requirements, providing legally defensible grounds for provisional ICO notification while the full investigation continues.
Forensic Chain of Custody
Every piece of evidence is collected and documented following forensic chain of custody standards, ensuring your investigation findings are admissible in regulatory proceedings and insurance claims.
ICO Breach Investigation Support
We have supported UK organisations through ICO breach investigations. Our team understands what the ICO expects and how to document a proportionate response that demonstrates good faith.
Data Subject Impact Assessment
Determining which personal data records were affected, the severity of the risk to data subjects, and whether notification to individuals is required under Article 34.
DPO Direct Support
Direct communication channel for your Data Protection Officer or General Counsel throughout the incident. We understand the personal accountability DPOs carry and structure our support accordingly.
Already 12, 24, or 36 hours into a breach without notifying the ICO? Contact us immediately. Late notification with documented reasons is far better than no notification. Our preliminary scope assessment is formatted for ICO reporting and can typically be delivered within 4 to 6 hours of engagement.

Post-Incident Vulnerability Assessment
After containing the breach, our offensive team assesses the vulnerabilities that need hardening and tests your patched environment to confirm the gaps are closed. Ongoing monitoring is available through our managed detection and response service or a dedicated Security Operations Centre. If you are unsure which model fits, see our MDR vs SOC vs SIEM comparison guide.
